PharFileInfo::decompress
(PHP >= 5.3.0, PECL phar >= 2.0.0)
PharFileInfo::decompress — Decompresses the current Phar entry within the phar
Description
This method decompresses the file inside the Phar archive. Depending on how the file is compressed, the bzip2 or zlib extensions must be enabled to take advantage of this feature. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed if the file is within a Phar archive. Files within PharData archives do not have this restriction.
Return Values
Returns TRUE on success or FALSE on failure.
Errors/Exceptions
Throws BadMethodCallException if the phar.readonly INI variable is on, or if the bzip2/zlib extension is not available.
Examples
Example #1 A PharFileInfo::decompress() example
<?php
try {
$p = new Phar('/path/to/my.phar', 0, 'my.phar');
$p['myfile.txt'] = 'hi';
$file = $p['myfile.txt'];
$file->compress(Phar::GZ);
var_dump($file->isCompressed());
$p['myfile.txt']->decompress();
var_dump($file->isCompressed());
} catch (Exception $e) {
echo 'Create/modify failed for my.phar: ', $e;
}
?>
The above example will output:
int(4096) bool(false)
